In this paper, we study nanostructure-covered laser induced periodic surface structures (NC-LIPSSs) on metals produced by femtosecond laser pulses incident at various angles. For the first time, we show that the dependence of NC-LIPSS period on the incident beam angle deviates significantly from tha ... [J. Appl. Phys. 108, 073523 (2010)] published Mon Oct 11, 2010.
